Tauroursodeoxycholic acid ,also known as taurocholic ursodeoxycholic acid, the chemical name is 3α, 7β-dihydroxy bile alkanoyl-N-taurine ,it is mainly present in the black bear bile, It is the active ingredient in bear bile landmark. It has many effects such as antispasmodic, anticonvulsant, anti-inflammatory and dissolve gallstones and so on.
Modern synthetic drug Tauroursodeoxycholic acid, it is the conjugated bile acid which is through anhydrosynthesis of the carboxyl of ursodeoxycholic acid and amino group of taurine . Foreign Tauroursodeoxycholic acid capsules are already on the market ,in 2007it is approved for sale in China as an import drug , it is mainly used for the treatment of cholesterol gallstones, primary sclerosing cholangitis, primary biliary cirrhosis and chronic hepatitis C virus hepatitis.
